Be it known that ll, @Hennes` l?. llfnrnvnn, a citizen of the United States of America, residing at Plymouth, in the county of `Wayne and State of Michigan, #have "invented certain new and useful improvements in Air-Guns, or' which the following is a specification, reference being had there-in to the accompanying drawings. y 1 1 The invention relates to air gunsyof that type known as pump guns in lwhichthe compression ofthe spring is eiectedby the sliding of a handle longitudinally of the barrel. This handle is connected with a lever mechanism `for actuating the movable `member that compresses the spring, and one ot the objects of the present invention isto obtain an improved and simpliiied construction in which :means is provided between the lever mechanism and the spring for actuating the latter from `the former witha decrease `in power of the lever mechanism and an increase `in rate of compression of the spring during a portion of the travel of the handle, and with anincrease in powerotthe lever mechanism and decrease in rate of compression of the spring during another portion of travel of the handle. nother object is to obtain means operated from` the handle guide `for permitting of the passage ot a projectile from the magazine into the true barrel. A further object is to obtain an arrangement of power storage and releasing mechanism which is attachable to and de-` tachable from the stock ofthe gun as a unit.

Still lother `objects of the invention reside in the means for connecting the stock to the barrel and inthe novel arrangements and combinations of parts as more fully herein-1` after set forth. i In the drawings:` y Figure l is asectional side elevation of the gun embodying myinvention, the actux located Intherecess M2 of theabutment C ating handlebeing in extended position; ,Y Fig. 2 is a sectional view therethrough l;` Fig. 3 is a similar view showing the actuating member in retracted position," y

A is the false barrel comprisin the forward and rear portions A and 2 rigidly secured to each other, the rear portion AZ having the depending side flanges A35 B is l`specificatimof iillittllltll DBC.. 3,1915. Appncanonfued Aprilia 1918. serial No. 228,507.

the stocle` @the spring located within the recessB of the stock, D the handle movable `longitudinally ofthe false barrel uponthe handle guide D', and `E is the lever mechanism connected tothe handle and" adapted to "compress the spring C, the lever mechanismi passing between "the depending side arnges-i3 ofthe falsebarrehl is the true barrell axially mounted `within the forward portion Ayoif` the false `barrel and-having the apertureli" in its rear upper `portion conneicting into the magazine chamber F2 whichcontains the projectiles. Gr `isthe cylinder` within the rear portion A2 ot the `false l barrel, provided lwith the upwardly and `downwardlyextending 'flanges Gr at its opposite ends which slidably engage the rear "portion: A2 and `are guided thereby. The cylinder G also has the axially-extending hollow tube G2 atitsforward end which slidablyengagesthetrue barrel Fand normallycloses the aperture F. H is the plunger slidably engaging the cylinder G and connected to the detent member l through the rod 1l-l. "This detent member extends transversely of the rear portion A2` of the false barrel andihas the upwardly `entending projection llslidably engagingthe rear portion A and guided thereby and also has thewportion lf2 extending between the side flanges A8 of thefalsebarrel. `The portion allyconnected` thereto and also has the rearward 'endslightly curved downwardly and engaging inthe recessB of `thestoclr and engagedby the spring C.

Thelspring "C with its abutment C', the searfl` and the triggerK areinclosed within the housing N, the searand trigger being pivoted therein.` The housing also `formsthe trigger guardli "and is detachably mounted within the recess B of the stock B and is the screw bolt O which entends through the `r"ea`r`7 portion y'ofthe `stock B and threadedly held in engagement therewith `by means of y engages the spring abutment N in the rear end of the housing. The head O of this screw bolt is located within the recess O2 formed in the rear kend of the stock. Thus it is seen that an arrangement of power storage and releasing mechanism is provided having the one housing which is attachable to or detachable from the stock of the gun as a unit.

For the purpose of readily and easily connecting the stock to the false barrel, the housing N is provided with the upwardlyextending flange P at its forward end which is located within the portion A2 of the false barrel and cooperates with the depending or downwardly extending flange Pthereon. The trigger gua-rd L slidably engages between the side plates A3 and is connected thereto by the 'screw P2. To withdraw the stock from the'barrel, the screw is removed and the stock andy barrel moved relative to each other to disengage the coperating flanges P and P.

The lever mechanism E comprises the link E pivotally connected to the handle D at Q and the L-shaped cam member or link rE2 pivotally. connected to the link E at Q. The opposite end of the cam member or link E2 is pivotally connected to the rear portion A2 of the false barrel at Q2 forward of the projection I upon the detent member. This arrangement of link E and @am member E2 forms a toggle-lever which in its normal position7 is extended 'so that the members lie adjacent to the false barrel and can be broken downwardly by a rearward movement of the handle D. The legs of the L- `shaped cam member or link halve the cam surfaces R and R which surfaces contact with the surface I3 of the detent member upon swinging about its pivot Q2 the cam member or link. In the normal position, the leg having the cam surface R extends transversely of the false` barrel A andl in the final retracted or broken position the leg having the cam surface R extends transversely of the false barrel. The cam surface R is rounded slightly so that upon movement of the handle D toward" the rear, the point of contact between the cam surface R and the surfaceI3 of the detent member progressively moves away from the pivot Q2.

In operation, to compressthe spring C the handle D is moved toward the rear which first breaks the toggle-lever E at. which time the detent memberI is but slightly moved, due to the contacting point between4 the cam surface R and the surface I3 of the detent member-being located relatively near to' the pivot 2; Uponffurther' movement of. the handleD the contacting, points between the cam-surface. R and the surface I-3 of the detent member progressively moves downward so-th'at the leverageprogressively decreases an'd the rate of movement-of.- the'- detent member I with the corresponding rate of movementV of the spring C progressively increases. At this time the spring C is under small compression so that the above conditions of operation are highly desirable. Upon still further movement of the handle D, the cam surface It contacts with the surface I3 of the detent member and the leverage increases and the rate of movement of the detent member I and also of the spring C progressively decreases. At this time the spring C is under greater compression, which is also constantly increasing, so that the progressive increase of leverage is highly desirable.

For the purpose of admitting the projectile S into the true barrel F from the magazine chamber F2, the handle guide D is slidably mounted in the strap T near the forward end of the gun and has a hooked connection with the forward lower flange G of the cylinder G. This handle guide is provided with the transversely extending pin U forward of the handle D and between the handle and the strap T. The handle guide also has the upwardly-extending projection or abutment U near its rear end and in the path of rearward travel of the pivot Q. The pin U and the projection or abutment U are spaced from each other a suiicient distance so that they are engaged by the handle D and the pivot Q, respectively, when near the ends of the forward and rearward movements of the handle. Upon rearward movement of the handle, the spring C is compressed as shown above and before the completion of the movement the pivot Q contacts with the upwardly-extending projection or abutment U thereby moving the handle guide D rearward which in turn correspondingly moves the cylinder G with its hollow. tube G2 so that the latter opens the aperture F in the true barrel F and permits of the passage of the projectile fw from the magazine chamber into the true barrel. Upon forward movement of the handle D and near the completion thereof the handle contacts with the pin U thereby moving the handle guide D forward which in turn correspondingly moves the cylinder G with its hollow tube G2 to close the aperture F. The forward movement of the cylinder is limited by the rear end of the forward portion A of the false barrel. The hollow tube G2 forces the projectile S into the contracted portion of the true barrel A. The gun is new in condition to be fired by pulling the finger K of the trigger l.

From the above description it is 'seen that an eliicient construction of air gun is provided in which the spring for the storage of power is comparatively quickly compressed and at the same time the power is applied when most needed. Also simple means is provided for the insertion of the projectile `into `the true Vbarrel guide. i
